“…It is a common practice in III–As/P planar light-emitting diode structures to use GaInP as the active layer. By introducing Al in GaInP, the bandgap can be increased all the way to 2.52 eV in AlP but which has an indirect bandgap . The Al/Ga ratio in lattice-matched AlGaInP can be tuned to be used as electron blocking layer keeping the (AlGa)/In ratio constant because the lattice constant changes only slightly with increasing Al due to similar lattice constants for AlP and GaP. , In planar structures, LEDs based on the AlGaInP material system are often grown on GaAs substrates, since (Al x Ga 1– x ) 0.51 In 0.49 P is lattice-matched to GaAs .…”

“…Vapor Deposition (MOCVD) (MARMALYUK et al, 2013) (BUCHERT et al, 2012). As combinações desses elementos bem como seus teores produzem diferentes comprimentos de ondas eletromagnéticas, conferindo ao LED uma variedade de cores.…”
